Through hole resistors have become an integral part of electronic devices, providing dependable voltage and current levels needed for functional designs. Providing power for low voltage, 5V and 3.3V boards, the PSM400JB–22R is designed to provide high quality current source functionality within a larger array of varying current densities.

The PSM400JB–22R is an axial leaded diode array that uses an SMD (Surface Mount Device) package suitable for automated assembly and handling, and is designed for use in high-density and high-current applications. It can be operated at temperatures up to 2000F (1000C).The PSM400JB–22R is a convenient, compact device with an overall size of 2.5mm by 1.3mm.

Built to support a wide range of voltage levels, the PSM400JB–22R is divided into two distinct operating regions. The first is the low-voltage region, where values range from 0V to few volts. In this region, the diode provides a medium voltage drop of 0.6V, allowing the device to remain in a low-impedance state. The second region is the high-voltage region, where voltages exceed a few volts. The PSM400JB–22R is designed to provide a high-voltage drop of >2V, reducing the voltage to a level where it can be safely handled by integrated circuits.

In terms of its current characteristics, the PSM400JB–22R is capable of providing current up to 15A when operated in the low voltage region. This makes it invaluable in applications such as DC-DC converters, boost-regulators, and voltage-referencing circuits. However, the PSM400JB–22R becomes an even more versatile device in the high voltage region, providing current up to 2A when it is used to convert higher voltage levels down to safer values.

The integration of resistors and rectifier diodes in one package makes the PSM400JB–22R device an attractive choice for a variety of high-power applications. It can also provide level-shifting that may be necessary for boosting currents up to voltage levels where further circuitry can be easily interfaced with. This feature makes the PSM400JB–22R ideal for analog circuits and high efficiency boost-regulators that require a reliable current source in order to remain functional.

By integrating a pair of diodes and resistors, the PSM400JB–22R is able to provide a high current source in a compact package, making it valuable for a large array of applications. The device can operate in both low and high voltage regions, allowing it to safely and reliably improve current regulation in a wide range of devices. Its small size and versatility make it a popular choice for use in an ever-increasing array of applications.
